Abstract
The utility model provides a maintenance unit that is arranged in heat exchanger heat exchange tube to change, the heat exchanger mainly constitute by shell, heat exchange tube, tube sheet and head, the maintenance unit constitute by an electronic milling cutter, it includes that one has a gun type casing that electronic mechanism was installed in, to the motor -operated switch, the front end of this gun type casing is provided with one overhanging, the location axle in the heat exchange tube mouth of pipe of can pegging graft, the preceding tip of gun type casing is installed between a pair of heat exchange pipe and pipe plate welding seam and is carried out the tool bit of polishing, the location off -axial of gun type casing front end is provided with one and polishes and turn -take, installs a convex tool bit of polishing forward on it, polish turn -take with the gun type casing in the installation be linked together by motor -operated electronic mechanism, it has a simple structure, uses convenient operation, and is swift high -efficient, neither can influence the welding seam of peripheral heat exchange tube, again can not the tube sheet mouth of pipe quality of damage own etc. Characteristics.
Description
Technical field
The utility model relates to a kind of maintenance unit for replacing heat-exchange tube in heat exchanger, belong to the maintenance apparatus technical field of chemical industry and pharmaceutical industry heat exchanger.
Background technology
Existing heat exchanger, especially the shell-and-tube heat exchanger that uses of chemical industry and pharmaceutical industry, through the use of certain time limit, some heat exchanger tubes can be subject to the reasons such as the corrosion of heat transferring medium and need repairing or change, generally, this maintenance and replacing are all after the weld seam of dependence manual polishing exchanger tubes and tubesheets, heat exchanger tube could be taken off and carry out keeping in repair and changing, but this manual mode of operation, often be difficult to control, the weldquality of easy other heat exchanger tube of destruction periphery and affect tube holes on tube sheet quality, the welding effect of rear heat exchanger tube is changed in impact, whole heat exchanger is made to there is potential safety hazard.
Summary of the invention
The purpose of this utility model is the deficiency overcoming prior art existence, and provide a kind of structure simple, use easy to operate, quickness and high efficiency, both can not affect the weld seam of periphery heat exchanger tube, the maintenance unit for replacing heat-exchange tube in heat exchanger of tube holes on tube sheet quality own can not have been damaged again.
The purpose of this utility model has been come by following technical solution, a kind of maintenance unit for replacing heat-exchange tube in heat exchanger, described heat exchanger forms primarily of shell, heat exchanger tube, tube sheet and end socket, described maintenance unit is made up of an Electric milling cutter, it comprise one with motor switch, in the gun-type housing of motor drive mechanism is installed, the front end of this gun-type housing is provided with overhanging, a pluggable locating shaft in the heat exchanger tube mouth of pipe, and the leading section of described gun-type housing is provided with the cutter head that weld seam between a pair exchanger tubes and tubesheets carries out polishing.
The locating shaft of described gun-type housing forward end is outside equipped with a polishing and turn-takes, and it is provided with a polishing cutter head protruded forward, and described polishing is turn-taked and being connected by motor-operated motor drive mechanism of installing in gun-type housing.
It is simple that the utility model has structure, uses easy to operate, quickness and high efficiency, both can not affect the weld seam of periphery heat exchanger tube, can not damage the features such as tube holes on tube sheet quality own again.
Accompanying drawing explanation
Fig. 1 is heat exchanger structure schematic diagram described in the utility model.
Fig. 2 is using state structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail: shown in Fig. 1, a kind of maintenance unit for replacing heat-exchange tube in heat exchanger, described heat exchanger forms primarily of shell 1, heat exchanger tube 2, tube sheet 3 and end socket 4, described shell 1 two side ends is respectively with import 5 and outlet 6, many heat exchanger tubes 2 horizontal in shell 1, shell 1 two ends are fixed with the end socket 4 with interface tube 7 that the tube sheet 3 of heat exchanger tube 2 and shell 1 two ends connect, and described end socket 4 is detachably fixedly connected with the both ends of shell 1 respectively by respective adpting flange 8.
Shown in Fig. 2, described maintenance unit is made up of an Electric milling cutter, it comprise one with motor switch 9, in the gun-type housing 10 of motor drive mechanism is installed, the front end of this gun-type housing 10 is provided with overhanging, a pluggable locating shaft 11 in heat exchanger tube 2 mouth of pipe, and the leading section of described gun-type housing 10 is provided with weld seam 12 between a pair heat exchanger tube 2 and tube sheet 3 and carries out the cutter head 13 of polishing; The cutter head 13 of this polishing is also referred to as milling cutter.
The locating shaft 11 of gun-type housing 10 front end described in the utility model is outside equipped with a polishing and turn-takes 14, it is provided with a polishing cutter head 13 protruded forward, described polishing turn-take 14 with being connected by motor-operated motor drive mechanism of installing in gun-type housing 10.
The utility model also can by special milling cutter, and the cutter head 13 of namely polishing is arranged on and is similar on the electrical equipment of electric hand drill, aims at the mouth of pipe of heat exchanger tube, uniform grinding weld seam, thus can change efficiently and keep in repair heat exchanger tube by simple and fast.
